Just a feed back: For me, I click on HTML(1) in the menu on the left, and it expands below the page. There seems to be a thin scroll bar to the right to scroll down, but I cant grab it to scroll down. Only arrow keys and mouse wheel work. IMHO, scroll bar needs some work. Edit: (1)Correction I click on HTML, then HTML5. Then the list goes below the bottom of the browser, then I cant grab the scroll bar. Sorry for any confusion.
